AYTDKNEYS United States Patent F SLASHERS AND THE LIKE William L. Freeze, Gastonia, N.C., assignor to Cocker Machine and Foundry Company, Gastonia, N.C., a corporation of North Carolina Filed Sept. 29, 1958, Ser. No. 763,873

4 Claims. (Cl. 28-28) This invention relates to slashers and the like, wherein the warp yarns, after being sized or otherwise treated, are collected on power driven take-up beams.

In connection with such apparatus, I aim to provide a simple means capable of ready and quick adjustment to accommodate and rotatably support beams of different widths without necessitating disconnection of the beam driving heads from the mechanism relied upon for its propulsion.

How the foregoing and other objects and attendant advantages are realized in practice will appear from the following detailed description of the attached drawings, wherein:

Fig. 1 is a fragmentary view in top plan of a slasher conveniently embodying the warp beam of our invention.

Fig. 2 is a side elevation looking as indicated by the angled arrows lI-II in Fig. l; and

Fig. 3 is a view similar to Fig. 1 with the warp beam drive adjusted for a warp beam of a different width.

With more detailed reference to these illustrations, the usual side frames of the slasher are designated 1 and 2, and extending between them at their front ends is a pair of vertically spaced cross rods 3 and 4, slidingly engaged upon the cross rods 3 and 4 for adjustment toward and away from each other are two forwardly projecting bracket arms 5 and 6 for supporting the warp beam generally designated 7 in operative position in the slasher as more fully explained hereinafter. Afiixed to the end of the arm 5 is a speed reducing gear unit 8 which may be of the worm gear type having secured, to its output shaft 9, a beam driving head 10. As shown, this driving head has a radial slot 11 for reception of the journal 12 of the warp beam 7, the other journal 13 of said beam being removably engaged in a split bearing 14 at the distal end of the bracket arm 6. The drive head may be of the construction disclosed in a separate patent application Serial No. 764,004, filed concurrently herewith by me and George Manning, and provided with locking means for closing the slot 11 over the beam journal 12 after placement of the beam in the slasher. As shown, the inner face of the head 10 is smooth and the outer side is recessed and radially ribbed. Rotary motion is transmitted to the beam 7 from an electric motor mounted fixedly immediately inward of the side frame 1, through a shaft 21 formed in two sections 22 and 23 of which the section 23 is telescopically engaged with the section 22. As shown, the section 22 of shaft 21 is connected by a universal joint 24 to the shaft 25 of the motor 20, and the section 23 by a universal joint 26 to the input shaft 27 of the speed reducing unit 8. During rotation of the beam 7 the driving head 10 functions as a blower, its radial ribs tending to direct a continuous stream of cooling air toward the speed reducer 8.

2,963,767 Patented Dec. 13, 1960 Due to the sliding connection of the brackets 5 and 6 with the cross bars 3 and 4, it will be seen that it is possible to use beams of different widths in the slasher as exemplified in Fig. 3 wherein is shown a beam 7a of a narrower width. To accommodate the smaller beam, the brackets 5 and 6 are simply slid further toward each other incident to which the component 23 of the transmission shaft 22 automatically telescopes further into the component 22 as will readily be understood from Figs. 1 and 3.

While the preferred embodiment of this invention has been described in some detail, it will be obvious to one skilled in the art that various modifications may be made without departing from the invention as hereinafter claimed.

Having thus described my invention, I claim:

1. In a slasher or the like having spaced side frames, a pair of beam journal supporting bracket arms slidably supported with capacity to be shifted toward and away from each other crosswise between the frames for the accommodation of beams of different widths, a right angle speed reducing gear unit at the distal end of one of said arms; a driving head secured to the output shaft of said right angle gear unit and adapted to releasably receive one of the journals of a beam, and a bearing at the distal end of the other bracket arm to reletasably receive the other journal of the beam, a motor stationarily supported on one of the side frames of the slasher, and a transmission shaft formed by two telescoping sections whereof one component is connected by a universal joint to the shaft of the motor, and the other component is connected by another universal joint to the input shaft of the gear unit as and for the purpose described.

2. The invention according to claim 1, further including blower means associated with the driving head to direct cooling air toward the gear unit during rotation of the beam.

3. The invention according to claim 1, wherein the outer side of the driving head is recessed and radially ribbed to function as a blower to direct cooling air toward the gear unit during rotation of the beam.

4. In a yarn Winding device having spaced side frames, a pair of beam journal supporting members which are supported with capacity for shifting movement toward and away from one another for the accommodation of beams of different widths, a reducing gear unit carried for shifting movement with one of said supporting members, said unit having an input shaft and an output shaft arranged at angles to one another, a driving head drivingly connected to the output shaft of said gear unit and adapted to receive releasably one of the journals of the beam, means carried by the other of said supporting members for rotatably receiving the other journal of said beam, a motor stationarily supported and operatively connected to the slasher, and a transmission shaft comprising a pair of telescoping sections one component of which is connected by a universal joint to the output shaft of the motor, and the other component of which is connected by another universal joint to the input shaft of the gear unit.
